First, it would be a breach of your Snuggle Partner Integrity Agreement to tell your client that you want to have sex with them. So, please never say that during a session. And, naturally, actually having sex with a client would not only be breaching your Snuggle Partner Integrity Agreement, it would also be illegal. So, of course, don’t do that.
Outside of a session, if you admit to a client that you want to be sexual with them and/or date them — then you should stop taking appointments with them and stop exchanging money with them for your time and physical affection.
